Detroit police have taken down a large illegal marijuana grow operation on the city's east side.
Narcotics unit lt. Jonathan Parnell says the 400 plants, with a combined street value of more than $900,000 were found.
An anonymous tip call led police to a warehouse on Van Dyke, just south of 8 Mile.
Police officers executed a search warrant just after 8:00 pm, where they discovered the giant setup - believed to be illegally supplying several Detroit area marijuana dispensaries.
No one was there at the time of the raid, but police say they have identified a suspect.
Some of the plants will be kept as evidence in the case and the rest destroyed.
